- the present invention relates to a non-aqueous emulsion which is useful as a topical lubricant.
- the oil-in-oil emulsion according to the present invention is composed of a stearine, a silicone and, optionally, a diluent such as a glyceride, and a silicone emulsifier.
- the stearine is present in an amount which is sufficient to provide a non-aqueous emulsion when the components are melted together and mixed until the emulsion is set.
- the silicone oil is preferably a dimethylsilicone which can be optionally endblocked with trimethyl siloxy groups, alkyl groups and aryloxy groups.
- the present invention relates to a lubricant for fibers or threads comprising the above- described non-aqueous emulsion.
- the present invention also relates to a fiber composition comprising a fiber and the lubricant.
- the present invention relates to a cream or ointment composition
- a cream or ointment composition comprising the non-aqueous emulsion and at least one active ingredient.
- the silicone oil employed within the present invention include dimethylsilicones which can be optionally endblocked with trimethyl siloxy groups, alkyoxy groups from C ⁇ -CS Q , and aryloxy groups.
- the preferred silicone oils are trimethylsilox endblocked dimethylsilicones, although silicones terminated with silanol endgroups may also be used.
- silicone compositions such as dialkylsilicones, diarylsilicones, alkylarylsilicones, and alkenylalkylsilicones may also be employed in the present invention.
- the silicone may be the aforementioned compositions which contain silicon mers having at least one substituent.
- the silicone composition may contain silicon mers with a alkylpoly(oxyalkylene) substituent.
- the silicone may be the aforementioned compositions which contain silicon mers with an aminoethyl, an aminopropyl, or an aminoethyl-aminopropyl substituent.
- the silicone comprises a trimethylsiloxy endblocked dimethylsilicones with viscosities in the range of 10 centistokes to 500 centistokes.
- Diluent fluids such as glycerides, hydrocarbons, esters, and alkoxylates may be employed in concentrations up to about 95%, although concentrations of about 25% are preferred for most applications.
- glycerides which can be employed in the present invention include canola (low erucic acid rapeseed oil) , rapeseed oil (high erucic acid rapeseed oil), soybean oil, jojoba oil, castor oil, cottonseed oil, coconut oil, palm kernel oil, palm oil, sunflower oil (low and high-oleic varieties) , fish oils (e.g. orange roughy oil) , fractionated palm kernel oil and soybean oils.
- the stearines which can be employed within the present invention include those stearines having a high melting point, i.e., above about 50°C (122°F).
- These stearines i.e., fully hydrogenated oils
- high melting waxes such as carnauba or candellia may be employed.
- Hydrogenated rapeseed stearine or hydrogenated- castor stearine are particularly preferred due to their great stability and ease of use.
- the amount of stearine employed within the present invention is that amount which is effective in providing the formation of a thixotropic non-aqueous emulsion when the components are melted and mixed together until set.
- the amount of stearine present allows for the creation of an emulsion which is extremely stable, i.e., very difficult to breakdown by known means.
- the emulsion can remain stable even though surfactants may be added in amounts which would breakdown most emulsions.
- the amount of stearine employed is less than about 40% by weight, with about 1 to about 5% by weight being more preferred.
- a silicone emulsifier (or surfactant) is optionally added to the emulsion in order to alter the viscosity of the mixture and/or increase the stability of the emulsion.
- the preferred silicone emulsifiers are orga o-modi f i ed silicones that contain polyalkyleneoxide groups.
- An example of a commercially available emulsifier is SIL ET 7001, manufactured by. Union Carbide.
- silicone emulsifiers i.e., any amount which does not prevent the emulsion from forming
- concentrations of about 0.25% to about 3% by weight are preferred.
- the non-aqueous emulsion according to the present invention can be made by conventional processes. For example, in one embodiment at least part of the silicone oil(s) to be employed is heated together with the desired stearine until melted. These components are then mixed together in an homogenizer and the remaining portion (if any) of the silicone oil is added. This final mixture is then mixed within conventional apparatus such as a homogenizer (e.g., a tissue mixer) until the emulsion is set.
- a homogenizer e.g., a tissue mixer
- a solid stearine in an alternative method of making the emulsion according to the present invention, can be mixed with a silicone fluid and size reduction can be effected by any mechanical means known in the art such as a Wearing blender.
- a first non-aqueous emulsion of a stearine in a first silicone oil can be prepared by a conventional method as described above.
- a second non-aqueous emulsion of a stearine within a diluent fluid such as a glyceride is produced.
- the first and the second emulsions are then mixed together in order to form the final non-aqueous emulsion.
- the silicone fluid, silicone emulsifier, and the stearine such as hydrogenated castor stearine are heated together and gently stirred while cooling. During the process of cooling, a stable emulsion forms.
- a thixotropic emulsion may be formed using the aforementioned techniques. Because of thixotropic rheology, these emulsions can be employed as topical lubricants for a variety of applications, e.g., lubricants for fibers. Advantages of this lubricant according to the present invention include: improved fiber-to-fiber cohesion during processing, and in the case of spandex fibers, reduced swelling and lubricant absorption because of very high viscosity at low shear conditions.
- compositions may be as lubricants on synthetic fibers such as spandex, polyester, nylon, polymethane, polybenzimidazole, polypropylene, acrylic, aramid, and polyethylene.
- synthetic fibers such as spandex, polyester, nylon, polymethane, polybenzimidazole, polypropylene, acrylic, aramid, and polyethylene.
- the composition may be applied to proteinaceous fibers such as silk or wool as well as natural or synthetic cellulosic fibers such as cotton or rayon.
- the composition may be applied by any means recognized in the art, for example, kiss rolls or capillary metering systems. Further, these compositions may be used on other fibrous assemblies such as sewing thread and textured filament yarns.
- lubrication of sewing thread has often been achieved by applying a molten lubricant composed of paraffin wax, esters such as glycerol monostearate, and * a dimethyl-silicone, often with a viscosity in the range of 100 cst-1000 cst.
- a molten lubricant composed of paraffin wax, esters such as glycerol monostearate, and * a dimethyl-silicone, often with a viscosity in the range of 100 cst-1000 cst.
- These "hot melt" lubricant compositions have several limitations. Only limited organic components, such as certain waxes and esters, may be incorporated into the formulation because of poor solubility in the silicone phase.
- compositions of the present invention are liquids at a wide range of temperature and, thus, may be applied at ambient temperatures.
- a further advantage of the present invention is that high concentrations of organic components such as glycerides may be readily incorporated.
- compositions can also be employed in numerous applications beyond those in the fiber and textiles industry.
- the absence of water and a broad temperature range in which viscosity is relatively constant indicates utility in other lubricant applications such as gasket and seal lubrication.
- compositions may be used in skin care compositions, with or without additional emollients, because their thixotropic nature imparts a desirable soft aesthetic when applied to the skin.
- the composition of the present invention can be employed within cleansing creams, emollient creams, hand creams, and as bases for sun screening preparations.
- the non-aqueous emulsions of the present invention do not contain bactericides.
- they are anticipated to have hypoallergenic properties.
- the compositions of the present invention may be extremely desirable as ointments and creams for wound care. The reason for this is that the water which is employed within conventional creams and ointments forms an ideal medium for bacterial growth during storage in containers as well as in the septic regions of wounds.
- the formulations based on the present invention can also be employed in preparations used as sunscreening preparations. The currently known preparations have limited durability in use because they are removed by perspiration and contact with water as the result of swimming, etc.
- compositions of the present invention as well as their affinity for skin, ' they can be employed within insect repellant preparations which have exceptionally long lasting efficacy.
- Example 1 Rapeseed stearine (2 grams) and L-45-10 silicone oil (98 grams) are weighed into a beaker. The mixture is heated in a microwave oven until the stearine melts. The mixture is then stirred intermittently with a tissue homogenizer until the stearine crystallizes (texture is thick and smooth, like shortening) .
- Example 2 Rapeseed stearine (2 grams) , Silwet L- 7001 silicone surfactant (0.25 grams) were weighed together into a beaker and melted over a flame. Approximately 50 grams of L-45-10 silicone oil was added to the melt and the mixture stirred with a tissue homogenizer. When the mixture began to set the remaining silicone oil (q.s. to 100 gram total weight of all reactants) was added and mixed until the stearine crystallized.
- Example 3 Refined, bleached, filtered canola oil (394 grams) and rapeseed stearine (8 grams) were mixed, heated until melted, and then blended with a tissue homogenizer until set (i.e. , .crystallized). This mixture comprises Part A of this method.
- Part B 250 grams L-45-500, 150 grams L-45-100 and rapeseed stearine (8 grams) were mixed, melted, and stirred with the tissue homogenizer until set.
- Part A (20 grams) and Part B (80 grams) were combined with stirring until homogeneous.
- Alternative compositions employing this method can encompass various ratios of Part A to Part B, including: 40% A:60% B; 60% A:40% B; 80% A:20% B.
- Silwet silicone surfactant one gram
- L-45-500 silicone fluid 74 grams
